Answer:
The correct answer is A. scavengers and B. producers
Explanation:
Two types of factors are found in a biome biotic and abiotic factor. All the living things in any biome comes under biotic factors like animals, plants, and microbes and all the non-living things present in the biome are non-biotic factors for example soil, temperature, air, water, salt, etc.
So biome is made up of both living and non-living factors. Scavengers are the organisms that feed on dead and decaying matter and producers are the organisms that make their own food. Most of the producers are plants.
So both scavengers and producers are living organisms therefore both are examples of biotic factors.
Mass does remain constant. A is true.
Only the form changes. ( I take that means that a solid is different from a liquid) and that is also true.
Kinetic energy changes. This one is kind of iffy. that means that the temperature will change. Temperature is a measurement of KE. If the change is so much as 1 degree or 1/2 a degree or a millionth of a degree, this is true. It's not very likeable though.
The last one is false. Chemical reactions produce new things. State change only produces something going (say) from a liquid to a solid. There's nothing new being created.

Answer:
D. that has a definite volume, but no definite shape
Explanation:
There are mainly three states of matter and these are:<em> solid, liquid and gas.</em>
Liquid has a definite volume because<u><em> its particles still remain in contact</em></u> although they're<em> moving freely</em>. On the other hand, such free movement of the particles render it to have "no definite shape." This is the reason why <em>liquid takes the shape of the container it is poured into. </em>
If you pour a<em> 500-ml liquid</em> into a<u> rectangular-shaped container</u>, it will look <u>rectangular</u>. However, its volume of<em> 500-ml</em> will remain the same.
